  • Let 𝖆 and 𝖇 be ideals of a commutative Noetherian ring R and M a finitely generated R-module of finite dimension d > 0. In this paper, we obtain some results about the annihilators and attached primes of top local cohomology and top formal local cohomology modules. In particular, we determine Ann(𝖇 Hd𝖆(M)), Att(𝖇 Hd𝖆(M)), Ann(𝖇𝔉d𝖆(M)) and Att(𝖇𝔉d𝖆(M)).

  • Local resources can be employed as an original resource for local revitalization. This study has investigated the local resource, and then categorized these to suggest the implication available to the industrialization. Local resources were classified into 5 categories(with 25 subcategories), including remains and ruins, ethnic custom, manners and customs, people, traditional food and the principal product, and the natural ecology environment. Three phases were carried out in this study. We made lists of local resources and analyzed applicable resources among the lists. Also, we selected the target resources for the survey in Gimpo, and also analyzed the application for industrialization. Of all these resources, 560 cases were first investigated, then 51 local resources were in-depth analyzed. Based on this result, the application plan was investigated, dividing the central resources and the connection resources.

  • Dental local anesthesia is important procedure for the elimination of pain during dental treatment. However, the pain during local anesthesia is one of the main source of fear to the patients. The cause of pain during dental local anesthesia includes soft tissue damage during penetration of the oral mucosa, pressure from the spread of the anesthetic solution, temperature of anesthetic solution, low pH of anesthetic solution, and the characteristics of the drug. Several concepts and devices introduced to date to reduce the pain during local anesthesia for dental treatment. In this report, devices that can reduce the pain during local anesthesia will be discussed.

  • This study is to analyze the local community-connected Education for Sustainable Development (ESD) programs that 17 clubs' students and teachers developed and implemented for their ESD club activities in elementary and middle schools. For this study, ESD elements in the programs are analyzed and the way of connection between the local communities' organizations and the ESD clubs is inquired. The process of ESD club activities is also analyzed and the change of students after the local community-connected ESD club activities is examined. Finally, the way of dissemination to local communities after ESD club activities is inquired. This study is to contribute to the practice of the local community-connected ESD in a way that develops core competencies in elementary and middle school students that will allow them to build a sustainable future in local communities.

  • Periodic variation of local paper structure was evaluated using two-dimensional fast Fourier transform (FFT) and spectral analysis. Since the periodic variation could originate from various sources and have different magnitudes and patterns depending on the origins, a complete analysis of local paper structure properties such as local grammage, local thickness, local apparent density and surface topography was proposed in this study. For a commercial copy paper, the individual periodic patterns for each local structural property were identified by using inverse FFT spectrums of the filtered spectrum. The spectral analysis of newsprint sample provided the period of variation quantitatively, which was useful in comparing the origins of the individual periodic patterns of the local structural properties.

  • This paper reviews the meat-type chicken breeding with local breeds in China. The quality chickens are defined as purebred final products of local breeds, and semi-quality chickens as crossbreds of local breeds with specialized broiler (sire or dam) lines from western breeding organizations. The present status of the chicken production and the market in China, in comparison with the western countries, is reviewed, indicating that there is large market demand for (semi-) quality chickens in the present and future China. Breeding for (semi-) quality chickens emphasizes the sensory quality of chicken meat. The present status of breeding for (semi-) quality chickens with the local breeds is illustrated, including breeding goals and the existing breeding programs. The potential role of local breeds in breeding programs in China is discussed in relation to both providing higher quality (than commercial hybrid broilers) of chicken meat for the local market and meeting the objectives of genetic resource conservation. Besides, further research topics on breeding for (semi-) quality chickens are suggested.

  • This article concerns a property of local rings and domains. A ring R is called weakly local if for every a ∈ R, a is regular or 1-a is regular, where a regular element means a non-zero-divisor. We study the structure of weakly local rings in relation to several kinds of factor rings and ring extensions that play roles in ring theory. We prove that the characteristic of a weakly local ring is either zero or a power of a prime number. It is also shown that the weakly local property can go up to polynomial (power series) rings and a kind of Abelian matrix rings.

  • Most local agencies such as counties and small cities continuously express difficulties in making technically and financially defensible decisions on their pavement infrastructure maintenance and rehabilitation. Unlike pavement systems managed by state highway agencies, the total lane-miles of many local pavements are significantly short and they are managed by a limited number of staff who typically have multiple responsibilities. Most local agencies also do not have historical pavement performance data and the lack of a systematic decision making framework exacerbates the problem. A structured framework and an easily accessible decision support tool that reflects their local requirements, practices and operational conditions would greatly assist them in making consistent and defensible decisions. This study fills this gap by developing a systematic pavement treatment selection framework and a spreadsheet based tool for local agencies. It is expected that the proposed framework will significantly help local agencies to improve their pavement asset management practices at the project level.

  • Fracture behaviors of pipes with local wall thinning is very important for the integrity of nuclear power plant. In pipes of energy plants, sometimes, the local wall thinning may result from severe drosion-corrosion damage. However, effect of local wall thinning on strength and fracture behaviors of piping system were not well studied. In this paper, the monotonic bending tests were performed of full-scale carbon steel pipes with local wall thinning. A monotonic bending load was applied to straight pipe specimens by four-point loading at ambient temperature without internal pressure. From the tests, fracture behaviors and fracture strength of locally thinned pipe were manifested systematically. The observed failure modes were divided into four types; ovalization, ovalization+cracking, local buckling and local buckling+cracking. Also, maximum load was successfully evaluated.
